Virtual and augmented reality (VR/AR) technologies are unlocking unique opportunities for individuals with visual impairments. These innovative solutions promise to overcome barriers related to accessing everyday services, workplace environments, educational materials and mobility training.
Nuremberg Institute of Technology in Germany has pioneered research in this space. Their findings reveal that an advanced tactile representation, coupled with realistic sound simulation in virtual environments, can substantially boost the utility of VR/AR for the blind and visually impaired.
Microsoft’s recent project ‘Canetroller’, illustrates this perfectly. It combines intricate soundscapes with comprehensive haptic feedback, enabling visually impaired individuals to explore a multitude of paths virtually.
A new era of multisensory experiences
The virtual cane of the ‘Canetroller’ allows visually impaired users to understand the size, appearance and spatial relations of objects. This hands-on experience prepares them to navigate similar environments in the real world, fostering better mobility skills.
In a broader context, integrating a clear understanding of our environment into computer systems can translate it into different mediums. With such technologies, visually impaired individuals could navigate cities using AR headsets and clothing designed to provide tactile feedback.
Current tech and its consolidation
Despite several of these technologies already being available as individual smartphone apps, their utilisation still requires hands-on interaction. For instance, visually impaired individuals need to frequently stop to capture images of their surroundings for AI-assisted hazard recognition. The consolidation of these technologies into one wearable device could significantly bolster user independence.
Low vision individuals often face difficulty identifying obstructions due to varying lighting, colours and backgrounds. However, an augmented reality solution can enhance the visual appearance of their surroundings, highlighting specific elements according to the individual’s visual impairment type.
The dawn of a revolution
Summarising, VR/AR technologies hold great promise to usher in a revolution for visually impaired individuals. While challenges persist, the amalgamation of persistent research, collaboration and innovation is breaking barriers.
The journey towards creating an environment where technology is an integral part of one’s senses is well underway. Empowering visually impaired individuals to navigate the world independently and confidently is becoming a reality, thanks to the strides in extended reality technologies.
